Answer:
(a) 0.71 mm
(b) 0.158 cubic cm
Explanation:
The width of one wire is the diameter of the wire.
(a) Let the diameter of each wire is d.
So, 10 d = 14.2 mm
d = 1.42 mm
radius of each wire, r = d/2 = 1.42/2 = 0.71 mm
(b) Length, L = 10 cm
The volume of the single wire is given by
Answer:
0.47 m
Explanation:
= Number of vibrations = 37
= total time taken = 33 s
= time period of each vibration
frequency of vibration is given as
Hz
= distance traveled along the rope = 421 cm = 4.21 m
= time taken to travel the distance = 8 s
= speed of the wave
Speed of the wave is given as
= wavelength of the harmonic wave
wavelength of the harmonic wave is given as

Answer:
1.0 m/s
Explanation:
First, convert to SI units.
0.30 km × (1000 m / km) = 300 m
5.0 min × (60 s / min) = 300 s
Speed is distance divided by time:
300 m / 300 s = 1.0 m/s
